I am not able to post pictures in Facebook comments using Firefox on my laptop. I am posting this here rather than in FB because I *am* able to post using Internet Explorer. When I click on the camera icon within the comment area nothing happens. In IE, doing the same opens up the ususal window to select the file I want to upload. Also, on my LG Android phone I can add photos to comments. Is there some setting in Firefox that could be the cause?
